On the `sm_distance` parameter of Poisson reconstruction #6238

Open stla opened 2 years ago

stla commented 2 years ago

Hello,

The average spacing of the Poisson reconstruction of my solid Möbius strip is 0.037. Here is the Poisson reconstruction with spacing = 0.05 (and default other parameters):

solidmobiusstrip005

Not very smooth. Now for spacing = 0.005:

solidmobiusstrip0005

On one hand it is smoother, but on the other hand it has some defaults.

No I keep spacing = 0.005 and I change sm_distance from the default value (0.375) to 0.9:

solidmobiusstrip0005_moresmdistance

The defaults have gone, and the computation time has decreased. I find strange that a change of a parameter decreases the computation time and increases the quality of the mesh. How would you explain that? I'm also wondering whether this default value of sm_distance is a good choice.
